MACHINE FOR TRIMMING SHOE-SOLES.

SPECIFICATION forming part of Letters Patent No. 282,857, dated August 7, 1883.

Application filed June 11, 1883. (No model.)

siding at Brockton, Plymouth county, Massachusetts, have invented certain new and useful Improvements in Machines for Trimming the Edges of Shoe-Bottoms, of which the follow ing is a specification, reference being had to the accompanying drawings, forming part hereof, in which- Figure 1 is a side view of an edge-trimmer having my improvements attached. Figs. 2 and 3 show details thereof, and Figs. 4' and 5 show modified forms.

Like letters of reference indicate the same parts in all the figures.

Machines of this class as heretofore made have been supplied with cutters similar to those shown by me, and with a sliding circular head or buffer, as at B, which buffer had to be pressed back by the shoe in the hands of the operator before the trimming could be done. This rendered the operation very unsteady, and I have in my invention endeavored to overcome this trouble by providing means whereby the cutters shall be fixed as to endwise adjustment when in operation; and to this end my invention consists in the devices hereinafter described, and pointed out in the claim.

Referring to the drawings by letter, A indicates the cutters, which are mounted in a revolving head, 0, having a stem,.D. These cutters are held inplace onthe head by a cap, a, and screw c. Surrounding the rear end of the cutters is a buffer-head, B, which slides backward and forward in the head, being guided in slots 1) therein. Attached to this sliding buffer-head and to the stem D are the adjusting devices.

In Fig. 1 I have shown the buffer adjusted by means of a bent rod or bar, E, on eachside of the head, provided in each end with a slot.

(Marked, respectively, 6 and f.) These ad. justing-irons are shown in side and front view in Figs. 2 and 3. The slots 6 play on a pin, 6, in the sliding buffer, and the slots f encompass screws F let into the spindle or stem D. \Vhen it is desired to adjust the buffer, which, as before stated, is held outward normally by spring-pressure, it is placed in proper position by hand, when the screw F is turned up and holds it there.

In Figs. 4 and 5 I have slightly modified the adj usting device. In Fig. ithe two ironsare joined by a ring, 9, encompassing the stem,

slots equivalent and corresponding to e and f in Fig. 1.. same.

The advantage of my construction is that The adjustment in-each case is the when the shoe is in position, as shown in Fig.
